Knee Joint

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Area of Science:

Orthopedics
Sports Medicine
Anatomy

Background:

Discoid meniscus is the most common congenital anomaly of the knee meniscus.
Its varied pathologies result in diverse clinical presentations.
Congenital discoid meniscus can lead to knee pain, clicking, and instability.

Purpose of the Study:

To review the pathology, diagnosis, and management of discoid meniscus.
To emphasize the importance of tailored treatment based on specific discoid meniscus pathology.
To highlight preferred surgical techniques for optimal outcomes.

Main Methods:

Review of current literature on discoid meniscus.
Analysis of diagnostic imaging modalities (radiographs, MRI).
Discussion of surgical techniques and intraoperative evaluation.

Main Results:

Discoid meniscus exhibits significant pathological variability.
Imaging, particularly MRI, is crucial for accurate diagnosis and pathology determination.
Intraoperative assessment is critical for surgical decision-making.

Conclusions:

Treatment for discoid meniscus must be individualized to the specific pathology.
Rim preservation and repair are preferred surgical strategies.
Preventing degenerative changes is a key goal in managing discoid meniscus.
